Electrowetting is now used in a wide range of applications from modular to adjustable lenses, electronic displays (e-paper), electronic outdoor displays and switches for optical fibers. Electrowetting has recently been evoked for manipulating soft matter particularly, suppressing coffee stain … See more Electrowetting is the modification of the wetting properties of a surface (which is typically hydrophobic) with an applied electric field. See more The electrowetting of mercury and other liquids on variably charged surfaces was probably first explained by Gabriel Lippmann in … See more Reverse electrowetting can be used to harvest energy via a mechanical-to-electrical engineering scheme. See more Optoelectrowetting, and photoelectrowetting are both optically-induced electrowetting effects. Optoelectrowetting involves the use of a photoconductor whereas photoelectrowetting use a photocapacitance and … See more The electrowetting effect has been defined as "the change in solid-electrolyte contact angle due to an applied potential difference between the solid … See more Another electrowetting configuration is electrowetting on liquid-infused film. The liquid-infused film is achieved by locking a liquid lubricant in a … See more For reasons that are still under investigation, only a limited set of surfaces exhibit the theoretically predicted electrowetting behavior. Because of this, alternative materials that can be used to coat and functionalize the surface are used to create the … See more WebDec 1, 2024 · Abstract Liquid metal is actuated against the force of gravity using low-voltage, low-power continuous electrowetting.

WebWe have fabricated the CEW actuator, silicone rubber pumping membranes and copper flap check valves, and have demonstrated actual liquid pumping up to 63 /spl mu/l/min at the applied voltage of 2.3 Vpp. The maximum pump pressure is about 600 Pa at the applied voltage of 2.3 Vpp with operation frequency of 10 Hz. Published in: Technical Digest. WebNov 15, 1998 · CEW is a surface-tension driven actuation mechanism that drives a liquid-metal droplet along an electrolyte-filled microchannel by controlling the surface tension of the liquid metal with electric potential. DRIE process enables us to use silicon dioxide microchannel instead of the previously reported polymer which raised the question of …
